Forescout: OT and IoT devices slow post-quantum migration

A Forescout report covering 2.5 million devices across 50+ organizations found that medical and industrial systems rarely support post-quantum algorithms: only 36% of PACS and 33% of electronic medical records support TLS 1.3. The "harvest now, decrypt later" risk forces firmware updates from vendors and device re-certification.

• Only 36% of PACS and 33% of EMR systems support TLS 1.3 with ML-KEM
• PQC-capable: 28% of IoT, 16% of OT and 6% of IoMT devices
• Over 5,500 medical information systems are exposed to the internet
• G7 urges completing PQC migration by 2030
